: DRP Technology

TI's DRP™ technology is a direct response to the dilemma wireless handset manufacturers confront: attracting new users by delivering compelling functionality to all market segments while...fulfilling user demand for less expensive, more power-efficient, smaller and lighter wireless mobile devices.

How does it work?

DRP technology achieves these seemingly opposite objectives by aggressively integrating handset electronics. TI is applying its digital expertise to the RF analog content of wireless handsets (which often account for up to 40% of the total board real estate). This includes the development of:

sampled-data processing techniques

digital phase locked-loops

switched-capacitor filters

oversampling converters

digital signal processors

that can assume the functions previously performed by analog amplifiers, filters and mixers.

Instead of a simple (and inefficient) transference of analog blocks into digital technology, DRP technology oversamples analog signals and processes them in the digital domain. The benefits of digital CMOS and deep submicron fabrication are captured.

What are the benefits?

As digital components achieve faster process switching speeds, handset designers can decrease the analog content of their designs. The oversampling rate of analog input signals can be increased, which reduces noise aliasing problems. The design of input networks can be relaxed.
